A number is divided into two parts in the ratio 1:3. If the larger part is 108 find the number?

The number would be 144 because when you divide 108 by 3 you get 36. 36+108=144

144

Step-by-step explanation:

To solve this question, we will have to represent the unknown number as y

The unknown number is then divided into two equal parts in a given ratio which is 1:3 and the larger part has 108 based on the ratio given we can deduce that the larger part is 3

To solve, firstly add the two ratio together that's 1+3=4

The next step is to multiply the larger part of the ratio multiply by the unknown number then divided by the total of the ratio

Here is the further solution

3/4*y=108

Cross multiply

3y=108*4

3y=432

Divide both sides by 3

y=144

Therefore the final answer is 144
